Hi mycha777,
Try to install TwonkyMedia Server. The current version 6.0.23 can read the movie covers as well. Download it from the following link = http://www.twonkyforum.com/downloads/6.0.23/
The install process is very easy. I suggest you to use these instructions --> http://wiki.dns323.info/howto:twonkyupnpserver
NOTE = To install TwonkyMedia, you must first enable a telnet server on the DNS-323.
Regards!
